題があった。However, various conventional devices (electronic devices) in each home have been individually connected to each other. For example, the telephone line was directly connected to the modem and the cable was directly connected to the decoder. As a result, for example, even when there are a plurality of personal computers at home, communication between them requires an external network. In addition, the image data received by the decoder is at most VCR (Video Castrecord Record).
To record the received image data with a personal computer, you can only record in r),
There is a problem that it is difficult to use many devices as one integrated system, such as the need for another dedicated device.
